Please do not make component or netlist changes directly in the PCB. In EasyEDA, the schematic is the master document. An accurate BOM can only be automatically generated from the schematic because it is only the Schematic Symbols that represent the full PCB Footprint, supplier and manufacturer information for a part. A PCB Footprint only represents footprint information and this may be used by many different Schematic Symbols so it does not represent a unique part. In other words there is a many Schematic Symbol to one PCB Footprint mapping whereas there is a one PCB Footprint to many Schematic Symbols mapping. Particularly with the large number of parts available in EasyEDA it is not practical to make a unique PCB Footprint for every part. In fact there are so many parts available from LCSC that they are not all fully represented as symbols in EasyEDA so some symbols still have to be placed into the schematic and then some of their attributes manually edited to fully represent the part. Therefore, changes **must** be made to the schematic first and then passed into the PCB using **Update PCB...** from the Schematic Editor or **Import Changes...** in the PCB Editor. Given where you are now, you have two choices. 1. Do **Update PCB...** from the Schematic Editor or **Import Changes...** in the PCB Editor and then tidy up the PCB. Then the PCB will match the schematic  therefore the BOM will match the schematic and the PCB. 2. Manually edit the BOM to match the the PCB.
